IPC: H03K5/26
Filed: 1986-12-26
Abstract: PURPOSE:To obtain perfect linearity within an operation range, by directly calculating the root of a specific equation showing the relation between the sampling value of an input signal and a pulse position. CONSTITUTION:A three-stage shift register 1 introduces an input signal subjected to A/D conversion having a pulse width T to output a continuously delayed signal. A shift clock generating circuit 2 introduces a reference trigger signal and outputs three clock signals of a cycle T/2 from the point of time t0 on the basis of said reference trigger signal as the clocks of the register 1. An operator 3 introduces the output signals x1-x3 of the third-first stages of the register 1 to output the value Y shown by formula. By this method, perfect linearity is obtained within an operation range.

Title: Manufacture of strained quantum well semiconductor light emitting device
Inventor: NISHIKATA KAZUAKI
IPC: H01L21/203
Filed: 1994-12-16
Abstract: PURPOSE: To form an active layer in which strain is sufficiently large and which has a strained quantum well layer having sufficient thickness by lowering the growing temperature of the active layer lower than that of a clad layer. CONSTITUTION: An active layer 4, a lattice-matched clad layers 2, 6 and light confinement layers 3, 5 are sequentially epitaxially grown in this order to be laminated on a substrate 1. The layer 4 has a quantum well layer 4a having a compression strain and a lattice-matched barrier layer 4b. The growing conditions are that the layers 2, 6, the light confinement layers 3, 5 and the layer 7 are grown at the upper limit temperature at which the epitaxial growth cannot be conducted by the isolation of In and the layer 4 is grown at the lower temperature than that. Thus, the growing temperature is lowered to use more number of the quantum wells as the active layer. Accordingly, the confinement amount depending upon the thickness of the layer is raised, and the carrier density is reduced, and hence the light emitting efficiency is raised as the whole.

Abstract: PURPOSE:To store extra exhaust heat in a hot spring well by providing water injection piping for injecting into the hot spring well water contained in a heat exchanger when cooling water is heated to above a predetermined temperature after passing through a heat exchanging portion for the cooling water. CONSTITUTION:When cooling water is heated to above a predetermined temperature (about 75 deg.C)after passing through the heat exchanging portion 2a of the cooling water exhaust piping 2 of a co-generation unit 1, a solenoid valve 12d is opened so that city water is supplied into a heat exchanger 4 via water feed piping 5.

A water head above the natural water level is applied to the inside of the well 7 by injection of the high-pressure water and the high-temperature water is returned and stored in the well 7 or an aquifer 7a. By supply of the city water into the heat exchanger 4 the valve 12d is closed when the temperature of the water contained in the heat exchanger 4 is stopped to less than 70 deg.C so that injection of the high-temperature water is stopped. The temperature of the water contained in the heat exchanger 4 is thereby maintained within a predetermined temperature range and also extra exhaust heat is stored in the well 7 etc.
